Windows 10: Unable to paste credentials into the elevated UAC prompt

I recently received a new laptop through work. I have full admin rights, but I have found that I am unable to paste anything in the UAC prompt whether I have regedit/gppolicy Secure Desktop enabled or disabled. I cannot disable UAC as it is against policy and I get a randomly generated password every 10 hours. I can paste credentials on other laptops that use Windows 10, but not on this one. I understand that this is a security policy that Microsoft enacted to prevent bad actors, but there has to be a work around of some sort. There must be a way to either remove the Windows patch/update that

UAC Elevation prompts?

Which is more secure regards to the UAC Elevation prompt?

And which one should I select for the Admin account?

Prompt for Credentials on the Secure Desktop or Prompt for Credentials?

 

How do I change the default administrator account for the UAC elevation password prompt?

I have set the "User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode" security policy in secpol.msc to "Prompt for credentials" for security purposes so that even when a user is logged in as an administrator
they must type their password instead of simply consenting to the UAC prompt. The only problem is that when the built-in Administrator account is enabled the UAC elevation prompt ALWAYS defaults to that account instead of the currently logged in local administrator
account, requiring the user to click "More choices" then their name before being able to use their own password to elevate. When performing repetitive administrative tasks this quickly becomes very annoying. It was my understanding the UAC prompt should remember
the last user account used, however that does not seem to be the case. How can I make the UAC elevation prompt default to the currently logged in administrator instead of the built-in administrator account?
